    Unable to Connect to Wireless Networks - Atheros AR928X

    I'm having real trouble with my laptop (Toshiba Satellite Pro P300-1FP) connecting to wireless networks since installing Ubuntu 12.10. I can view networks but can't connect to any - I enter the security key and it takes an age to process before telling me that it hasn't worked. This is with Ubuntu's default network manager and Wicd.

    I've tried everything I can think of (admitedly not a great deal, I'm still very inexperienced with Ubuntu) and have trawled these forums for several days trying every possible solution in every thread I could find that even closely resembled my problem. I'm very keen to get the wireless working on this laptop - I really don't want to have to go back to Windows ...

    I'm not sure what information will be needed to correct this problem, but here's what I have just now:

    Wireless Adaptor: Atheros AR928X

    Re: Unable to Connect to Wireless Networks - Atheros AR928X

    Try to deactivate the hardware encryption of th driver:
    Code:
    echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf
    sudo modprobe -rfv ath9k
    sudo modprobe -v ath9k
    Additionally, I recommend using pure WPA2-AES encryption instead of WPA only

    Thanks for the suggestions, but this didn't seem to work

    Edit: Is this what's expected?

    Code:
    hollie@hollie-lt:~$ echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf

    Did you change the encryption mode?

    Do you mean the network encryption? The network with WPA encryption was an access point at work - I also cannot connect to my home router (which uses WPA2).

    *Shameless bump*

    Any other thoughts? I'm completely stumped ... Is it worth mentioning that I tried installing Ubuntu 12.04 as well as the latest release of Joli OS (1.2.1?) and neither of them worked either? I can confirm that the adapter worked a week ago before I put Ubuntu on the laptop, so it's (probably) not a failure of the wifi card.

    Sorry to bump this again - anyone have any thoughts on this? It's really frustrating, and I've tried so many things (and reinstalled Ubuntu so may times). Am I better off trying a different distro? I tried ndiswrapper but that didn't seem to work either (though that could have been an error on my part).

    First, bring up a terminal (Ctrl+Alt+T is the usual hotkey). Then type
    Code:
    sudo iw wlan0 scan | grep SSID
    If your network is listed, proceed:
    Code:
    sudo wpa_passphrase "mywireless_ssid" "secretpassphrase"
    sudo wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf &
    If this succeeds, then enter:
    Code:
    sudo dhclient wlan0
